I have the Frigidaire twins, and here are my opinions on your questions that I can answer: 1) They perform very well, keep produce fresh for longer than I'd imagined possible. 2) The model I bought has non-reversible handles. 3) Mine are not installed side-by-side, so I don't know about overall width, but only you can decide whether your kitchen will have enough storage if you give some up for refrigeration. 4) We are a family of 2-7 adults and one child, reaching the max over holidays. I cook breakfast and dinner from scratch just about every day with lots of fresh ingredients. The capacity is fine for us, even around Thanksgiving.
